Abstract
Objectives: Acute pancreatitis (AP) may reveal intraductal papillary mucinous neoplasms of the pancreas (IPMN). The aims were to describe the characteristics of AP associated with IPMN and to compare patients with AP with those without AP. Methods: All patients who underwent surgery for IPMN between 1995 and 2006 were retrospectively studied. Clinical, imaging, and histological data were collected. The clinical and radiological severity of AP, the number of episodes, and recurrence after surgery were assessed. Results: One hundred eighty-five patients were included. Sixty-four (34.6%) had at least 1 AP (median, 2; range, 1-10). The median Balthazar score was 1 (0-6). Imaging analysis showed no difference between the 2 groups except for the presence of a mass. Branch duct IPMNs were more frequent in the AP group (74.4% vs 45.3%, P = 0.001), whereas combined IPMNs were more frequent in the non-AP group (45.3% vs 21.5%, P = 0.001). There was no difference in the grade of dysplasia between AP and non-AP groups: carcinoma, 45.3% versus 56.2%; benign IPMN, 54.7% versus 43.8% (P = NS), respectively. Conclusions: Acute pancreatitis occurs in 34.6% of patients with IPMNs. Acute pancreatitis is not severe and often recurs. Histology showed no difference between the 2 groups.
